spring-data-redis 怎么监听消息队列有消息来了

 

pom.xml中添加如下配置
添加版本配置
<properties>
  <jedis.version>2.8.1</jedis.version>
  <spring-data-redis.version>1.7.2.RELEASE</spring-data-redis.version>
  <commons-pool2.version>2.2</commons-pool2.version>
</properties>
    <!-- jedis -->
    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>${jedis.version}</version>
    </dependency>

    <dependency>
      <groupId>org.apache.commons</groupId>
      <artifactId>commons-pool2</artifactId>
      <version>${commons-pool2.version}</version>
    </dependency>

    <!-- https://mvnrepository.com/artifact/org.springframework.data/spring-data-redis -->
    <dependency>
      <groupId>org.springframework.data</groupId>
      <artifactId>spring-data-redis</artifactId>
      <version>${spring-data-redis.version}</version>
    </dependency>

properties文件中添加如下配置
#redis配置
redis.host=192.168.1.150
redis.port=6379
redis.password=redis
redis.timeout=2000
redis.max_total=100
redis.max_idle=20
redis.min_idle=5
redis.test_on_borrow=true
redis.test_on_return=true

applicationContext.xml中添加如下配置：
<!-- Jedis 连接池配置-->
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
    <property name="maxIdle" value="${redis.max_idle}" />
    <property name="maxTotal" value="${redis.max_total}"/>
    <property name="minIdle" value="${redis.min_idle}"/>
    <property name="testOnBorrow" value="${redis.test_on_borrow}" />
    <property name="testOnReturn" value="${redis.test_on_return}"/>
</bean>

<!-- Jedis ConnectionFactory 数据库连接配置，注意id名称必须为redisConnectionFactory-->
<bean id="redisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
    <property name="hostName" value="${redis.host}" />
    <property name="port" value="${redis.port}" />
    <property name="password" value="${redis.password}" />
    <property name="poolConfig" ref="jedisPoolConfig" />
</bean>

定义消息发送者（生产者）：
@Component
public class SendMessage {

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    public void sendMessage(String channel, Serializable message) {
        redisTemplate.convertAndSend(channel, message);
    }
}

定义消息处理者（消费者）：
public class ListenMessage {
    public void handleMessage(Serializable message){
        System.out.println(message);
    }
}

调用：/queue/redis
@Controller
@RequestMapping(value = "/queue")
public class QueueController {

    @Autowired
    SendMessage sendMessage;

    @RequestMapping(value="/redis")
    public void redis(){
        for (int i = 0; i <1000; i++) {
            sendMessage.sendMessage("java",i);
        }
    }
}
